IMPROVED HYDRAULIC BRUSH.

Specification forming part of Letters Patent No. 48, I67, dated January31, 1865.

To all whom it may concern:

Be it known that I, THOMAS .WELHAM, formerly of Nebraska, but now ofWashington City, District of Columbia, have invented a new and usefulBrush for Washing Windows, 850., which I style a Hydraulic Brush and Ideclare the following to be an exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, making a part of this specification, in which--- Figure1 represents the construction of the brush; Fig. 2, the chute, and Fig.3 the shape of the buckets of the revolvingwheel.

The nature of my invention consists in the arrangement and combinationof a revolving brush and revolvingwater-whee-l attached to the point ornozzle of ordinary hose for .the

purpose of washing windows, 85c.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation, as follows:

A represents a water-spout or ordinary hose commonly attached'to ahydrant or head of water.

' 3 is the hose-pipe or nozzle that is screwed to the end or point ofthe hose.

0 is a circular boxwith a partition, 1), having two openings, E E, thatform a chute for the water upon the angular buckets Gr, above.

These buckets I intend to attach to the under side or periphery of thebase H of the brush I. A vertical pin or shaft, J, is permanentlyfastened to the center of the partition D, and projects through thecenter tube of the buckets G and base 11 of the brush, and is the axleupon which the buckets, base, anclbrush re volve.

I is the brush, made round and formed of bristles in the usual mode. Thebuckets and brush are secured to the axle or shaft J by a common washerand pin, L.

As the water passes through the nozzlefof the hose it is forced throughthe chutes E E, and, striking against the buckets Gr, revolves thebuckets and brush, and flows through the aperture M of the base H in aspiral column from the top of the brush with the full force of thewater, so as to enable the brush to be? used with the best efi'ect forwashing windows or any parts of buildings requiring quick andcompletewashing and cleaning, or carriages, buggies, &c.

What I claim as my invention, and desire to secure by Letters Patent,isv The arrangement and combination of the revolving brush and therevolving Waterwhecl attached to the point of a water-spout or hose, asherein described, and for the purposes set forth.
